About C92

C92 is the ICD-10-CM diagnosis code for myeloid leukemia. It belongs to block C81-C96 (malignant neoplasms of lymphoid, hematopoietic and related tissue) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: C92.0 (leukemia), C92.1 (BCR/ABL-positive), C92.2 (BCR/ABL-negative), C92.3 (sarcoma), C92.4 (leukemia), C92.5 (leukemia), C92.6 (11q23-abnormality), C92.9 (unspecified) and 2 more.

Don't report C92 together with the conditions in its Excludes1 note: personal history of leukemia (Z85.6).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
